qwelly [4]

Answer:

The answer is "2793 miles"

Step-by-step explanation:

In this firstly we convert degrees to radians, which can be defined as follows:

\to \theta =\frac{40^{\circ} \times \pi }{180^{\circ}}

       =\frac{ 2\pi  }{9}

Now calculating the distance:

=\frac{2\pi }{9} \times  4000\\\\= \frac{8000 \pi }{9}

=\frac{8000\times 3.14 }{9}\\\\ = \frac{25120}{9}\\\\=2793 \ miles

A florist is arranging flowers in vases. There are 4 red flowers and 5 white flowers in every vase. The florist wants to make on
vichka [17]

There will be 72 flowers in total in the large arrangement.

Step-by-step explanation:

No. of red flowers in vase = 4

No. of white flowers in vase = 5

Ratio of red flowers to white flowers = 4:5

No. of red flowers in large arrangement = 32

No. of white flowers in large arrangement = w

Ratio of red flowers to white flowers = 32:w

Using proportion;

Ratio of red flowers to white flowers :: Ratio of red flowers to white flowers

4:5::32:w

Product of extreme = Product of mean

4*w=32*5\\4w=160

Dividing both sides by 4

\frac{4w}{4}=\frac{160}{4}\\w=40

Total flowers in large arrangement = Red flowers + white flowers

Total flowers in large arrangement = 32 + 40 =72

There will be 72 flowers in total in the large arrangement.
